ANTENNA CONNECTION
If

antenna
may
be
sufficient
to
obtain
a
clear
picture.
The
use
of
an
external
antenna
Is
recommended
especiaity
in
difficult
reception
areas
(inside
steel-frame
buildings,
in
mountainous
areas,
or
at
great
distances
from
the
transmitter),
VHF
and
UHF
antennas
with
separate
lead-in
wires,
or
a
combination
VHF-UHF
antenna
with
a
single
lead-in
wire
may
be
used.
When
a
combination
VHF-UHF
antenna
Is
In
use,
the
signals,
separated
by
a
VHF-UHF
signal
splitter,
are
fed
to
the
VHF
and
